INTRODUCTION Multiple sclerosis is an inflammatory disease involving the occurrence of demyelinating, chronic neurodegenerative lesions in the central nervous system. We studied vestibular evoked myogenic potentials (VEMPs) in this pathology, to allow us to evaluate the saccule, inferior vestibular nerve and vestibular-spinal pathway non-invasively. METHODS There were 23 patients diagnosed wi...

Vestibular diagnostics and therapy ist the mirror of technological, scientific and socio-economics trends as are other fields of clinical medicine. These trends have led to a substantial diversification of the field of neurotology.The improvements in diagnostics have been characterized by the introduction of new receptor testing tools (e.g., VEMPs), progress in imaging (e.g., the endolymphatic ...

OBJECTIVE We investigated the potential of galvanic vestibular stimulation (GVS) to quantify lateralised asymmetry of the vestibulospinal pathways by measuring balance responses to monaural GVS in 10 subjects with vestibular schwannoma and 22 healthy control subjects. METHODS Subjects standing without vision were stimulated with 3 s, 1 mA direct current stimuli delivered monaurally. The mean ...

Extracellular single neuron recording and labelling studies of primary vestibular afferents in Scarpa's ganglion have shown that guinea-pig otolithic afferents with irregular resting discharge are preferentially activated by 500 Hz bone-conducted vibration (BCV) and many also by 500 Hz air-conducted sound (ACS) at low threshold and high sensitivity. Very few afferent neurons from any semicircul...

In 2013, a 70-year-old male was admitted with an acute episode of vertigo, nausea, and vomiting with duration of one day. The patient's background included prehypertension, vitiligo, left ventricular hypertrophy, and Sjögren's syndrome. He denied any previous episode of vertigo or migraine manifestations. Neither hearing loss nor tinnitus or otorrhea was detected at the time of evaluation. No n...

background and aim: motion sickness (ms) is usually generated when there is a mismatch between the senses which serve balance. one of these senses is related to vestibular system, so it is highly possible that ms reflects in vestibular test results. but there are some conflicts in correlation between vestibular findings and ms. thus, the objective of this study was to provide an overview of ves...

OBJECTIVES For a reliable interpretation of left-right difference in Vestibular evoked myogenic potential (VEMP), the amount of sternocleidomastoid muscle (SCM) contraction has to be considered. Therefore, we can ensure that a difference in amplitude between the right and left VEMPs on a patient is due to vestibular abnormality, not due to individual differences of tonic muscle activity, fatigu...

OBJECTIVES/HYPOTHESIS This study aimed to evaluate the changes in electrocochleography (EcohG) measurements after intratympanic (IT) dexamethasone therapy and to correlate them with the long-term effects on the control of vertigo. STUDY DESIGN Prospective outcomes research. METHODS This study included 62 patients with unilateral Ménière's Disease (MD) refractory to medical therapy for at le...

Vestibular migraine (VM) is one of the most common causes of episodic vertigo. We reviewed the results of multiple vestibular function tests in a cohort of VM patients who were diagnosed with VM according to the diagnostic criteria of the Barany Society and the International Headache Society and assessed the efficacy of each for predicting the prognosis in VM patients. A retrospective chart ana...

OBJECTIVE To investigate the vestibular evoked myogenic potentials (VEMPs) resulting in benign paroxysmal positional vertigo (BPPV) patients and to verify its clinical applications in BPPV. STUDY DESIGN A prospective study. SETTING Tertiary referral dizziness center. PATIENTS Forty-one patients with diagnosis of BPPV and 92 healthy volunteers who underwent VEMP testing. INTERVENTION Pat...
